I've worked a little bit more and filling in the feathers. I erase most of the plain pencil as I go, then add the colored pencil bit by bit. I've added some blacks and grays and orangey colors and he's starting to fill out. I add whites both under and on top of the other colors, though it's usually much easier to only add it under. Some colored pencils are slicker than others and the white just just doesn't want to adhere. More tomorrow!
